To the Editor:—
In a recent paper concerning griseofulvin therapy in tinea capitis, Zaias et al (198:805, 1966) point out that their attempts at treatment with a single (3-gm) dose of griseofulvin or a course of 1 gm a week for four weeks resulted in a low cure rate which was hardly different from that found in a group which was not treated with griseofulvin. They point out that there are still large epidemics of tinea capitis in elementary schools despite the availability of griseofulvin as an effective oral treatment, and their own rate of cure goes some way to explain the continued presence of such epidemics.Those who treat ringworm of the scalp should remember that shaving of the scalp is perhaps the crucial factor which decides whether or not tinea capitis is responsive to treatment.
